LED Indicators
This document describes units manufactured after 14 March 2005. See the prior version
of this document for information about units manufactured on or before that date.
Whenever the E1 connection has lost link or has presented an E1 Alarm, the Ethernet
link will automatically be disabled (as indicated by no illumination of the Ethernet 100,
Act and Lnk LEDs). Upon reestablishment of the E1 connection, the Ethernet link will be
reinstated and the Ethernet LEDs will reflect current Ethernet Status.

LED State Indication Additional Information
E1
Connection
Lnk Flashing*
Green E1 connection is
established and active Traffic is flowing.
Solid
Green Problematic E1
connection A connection exists but there
is indication of a problem with
the E1 line.
No
Illumination Loss of Synchronization
(LOS) – The incoming
connection to the unit
has been lost; no data is
being received. If the outgoing connection
from the unit has also been
lost then the unit's partner
ENE2000 will have LOS as
well.
E1
Connection
Alm No
Illumination E1 is operational An established E1 link has no
alarm indications and is
operational unless the E1 Lnk
LED remains unlit as well, in
which case the ENE2000 has
LOS.
Solid
Amber Remote Alarm Indication
(RAI) – The outgoing
connection from the unit
has been lost; no data is
being transmitted. The unit's partner ENE2000
has lost its incoming
connection and has LOS.
Pulsing*
Amber Alarm Indication Signal
(AIS) – An indirect
connection has been
lost; the unit may no
longer be receiving data
from its partner
ENE2000. The unit's partner ENE2000
has lost a connection with an
intermediate device and has
LOS or RAI.
Power Solid
Green ENE2000 is operational If the Power LED is not
illuminated, it is unlikely that
the ENE2000 is receiving
power and therefore none of
the LEDs will be illuminated.
